IMPROVEMENT IN MECHANISMS'FOR REVERSING THE MOTION OF THE BEDS 0F METAL-PLANING MACHINES.

- Specification forming part of Letters Patent No- 178,209, dated May 30, 1876; application filed May 16, 1876.

To all whom it may concern;

Be it known that I, ULAUS VAN HAAGEN, of

Philadelphia, Pennsylvania, have invented certain Improvements in Metal-Planing Machinery, of which the following is a specification:

My invention relates to the driving and reversing gear of metal-planing machinery; and the main object of my invention is a regular and uniform reciprocating movement of the sliding bed, an object which'I attain by the mechanism which I will now proceed to describe, reference being had to the accompany- Figure 1, Sheet 1, is a side view of 'my improved driving and reversingmotion for metalplaning machines; Fig. 2, a vertical section on the line 1 2, Fig. 1; Fig. 3, a sectional plan; Fig. 4, an enlarged sectional View of part of Fig. 3; Figs. 5 and 6,.detached views of parts of the machine. a

A represents one of the fixed bearings for the main shaft B of a metal-planing machine,

and this shaft, which extends across the permanent bed of the planer, is furnished with a friction-wheel adapted to grooves on the sliding bed, as described in the Letters Patent granted to myself and A. Van Haagen on the 18th day'of'Jnne, A. 111872. To this main shaft 5 of the planer are secured the largebeveled friction-wheel D and the smaller beveled friction-wheel E, the former gearing into the pinionD, and the latter into the pinion E, both pinions being. loose on a shaft, F, which has its bearings in acasing, A, secured to the fixed bearing A' of the shaft B, the said shaft F being furnished with a cone-pulley, 'w, for receiving a driving-belt. (See Fig. 3.) The beveled pinion D has a bush, (1, adapted to the shaft F, andto the faceof the pinion is secured a stud, b, projecting into an annular recess, (1, in the clutch-wheel Gr, without touching either the sides or bottom of the said recess,.which will be especially referred to hereafter. Into the hub of, the clutch-wheel G is screwed a steel ring, 0, having teeth adapted to like teeth on the sliding clutch H, Which is armed with teeth at both ends, and is controlled through the medium of a shaft, I, an

tubular throughout a portionof its length. A key, f, is driven tightly through the clutch.

and through the shaft 1, and is arranged to. slide in a slot in the tubular shaft, which insures the rotation of the clutch with the latter, but permits the said clutch to be moved to and fro freely to a limited extent. ring,-e, similar to the ring 0, above alluded to, is screwed onto the bush of the beveled pinion E, and this ring has teeth adapted to like teeth on the clutch. When the clutch H is in gear with the ring 0 a fast rearward motion will be communicated to the sliding bed of the planer through thebevel-pinion E,-

wheel E, and shaft B; but when the clutch is in gear with the ring 0 a slower forward mo-.

tion will be'imparted to the sliding bed through the bevel-wheels D and D, and the said shaft 3. The shaft I referred to above as the medium through which the clutch is controlled,

1 The tubular rod Khas an arm, h, the outer end of which is so adapted to the shaftI that it can slide thereon to an extent limited by collars n 'n on the said shaft. therod J is adapted to the upper en of an arm, g, on a shaft, L, and a similar arm, 11, on

the tubular rod K is adapted to the upper end of an arm, g, on the tubular shaft M, the

latter having one of its bearingsin a projection, 8, on the casing A, and the shaft L;

having one of its bearings on'a pro ection, s, r

on the same casing. (See Fig. 2.)

The tubular reversing shaft M extends across and has its other bearing. on the per-1 manent bed of the planer, and'is operated from the sliding bed, a stop on the latter turn-= ingthe shaftM to a limited extent in one direction at the termination of one movement" of the bed, and a similar stop on the same bed, when the latter has reached the limit of I its reverse movement, turning the same shaft to a limited extent in the contrary direction.

A steel An arm, 12, on"

The devices by which the sliding'bedofa planin gm achine is caused to operate a re.vers

ing-shaft is too well known to demand illustration in the accompanying drawings, The

shaft L also extends across the permanent bed of the machine, and is furnished with a lever to be operated by hand. N, best observed in Figs. 2 and5, issecured to the reversing-shaft M, and this arm contains A- tubular'arm,

a sliding block, it, bearing on a spring in, the. arm, the block carrying a roller,-e, which is caused by the said spring to bear againsta pointed stud, u, secured to the permanent casing A. The object of the tube 3 (shown in Figs. v3 and 4) is to maintain thepinion E and clutch-wheel G at their proper distanceapart from each other.

As shown at Fig. 4, the-clutch H is in gear with neither of the pinions D'- orE, and .con

arinto turn beyond ;the Iimit'to .whichit had been moved by the positive; action ofthe slid-,

ing bed of .the planer, and thi's additionali movement is transmitted, from the. shaft M through the arm q, arm ,1), tubularrod K,' tothe arm h, which, bearing against the collar; n, moves theshaft I far enoughin the direetion of the arrow, Fig. 1, to suddenly.throw.

in.conjunctionwith the. pointed studw, again movetheelutch into gearwith theclutch.

wheel G, and, consequently with the pinion D, and the slidin'ghed of the planer will re- QQmmBnce itsslow forward movement.

It will be observed, on reference to Fig. 6,:

that the continuityof the annular groove in the clutch-wheel Gr is interrupted by a. crosspiece, 6, between which and the stud b on the wheel 1) intervene a series of spiralsprings,

malternating with sliding blocks 00!. When the. clutchH is throwninto gear with the clutch-wheel G, the latter turns in the directionotlthe arrow, Fig. 6 5 hence the motion of the clutch-wheel must be transmitted to t1 6 W.heel D through the elastic medium which intervenes between the cross-piece i and the stud-b,.and-this elastic. medium absorbs the shock consequent upon the sudden reversingotlthe bed of the planer, and at a timewhen its slow motion suddenly ceases, and its quick motion as suddenly commences.

This is an important feature of my invention, as it insures the-prompt and decisive engagementof the teeth-of the'clutch into those of the clutch-wheel G, and prevents the wear and tear of parts which would necessarily occur in' the absence of the cushion contained in the clutchwheel. arrzulgement may be applied tothe pinion E.

The same cushioning Blocks-of? rubber may besubstituted for the spiral spring; but. I prefen the latter, as they have-beenfou LldllllOSt serviceable in;.practice.

Although I have shown and described frictionwheels .as, the- ;medium; through which motion is.communieatedfrom. the driving to, the m ain shait, and although I;,prefer thesewheels, the

devices used in; connection therewith may beretained ,ifaordinary. cog-wheels are substituted fo -the; friction-wheels shown.
